About Add a Watermark to a PDF
Enter your text and choose size and opacity. The watermark is drawn diagonally across each page with an embedded font that supports many accented letters. It helps mark drafts and confidential documents before sharing.
FAQ
Can the watermark be removed later?
Anyone with PDF editing software may be able to remove it, so it deters rather than prevents misuse.
Are my files uploaded to a server?
No. Everything runs in your browser; your files and text never leave your device.
Is it free? Do I need an account?
The tool is free and needs no registration.
Does it work on a phone?
Yes, in modern desktop and mobile browsers; large files depend on your device power.
